Application filed Decembe 2.2, 1921. Se ial No. 524,100.

To all whom it may concern:

Be it known that we, EARL T. WINGET, I'IARVEY E. BRADLEY, and MORLEY G.WALTER, citizens of the Umted States,

residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have in vented certain new and useful Improvements in Signalsfor Motor Vehicles, of which the'following is a specification.

Our invention relates to signals for motor vehicles, and an object is toprovide a device by means of which the driver may readily indicate themanner in which he intends to vide a device which will give signals ofdifferent character according to whether the observer is at the front orat the vehicle.

The full objects and advantages of our invention will appear inconnection with the detailed description, and the novel featuresembodied in our inventive idea will be particularly pointed out in theclaim.

- In the accompanying drawings which illustrate the application of ourinvention in two slightlydifferent forms, F lg- '1 is a rear elevationalview of our device secured to a windshield post of an open-type of motorvehicle. Fig. 2 is a view in horizontal section on the line 2-2 ofFig. 1. Fig. 8 is a view in section on the line 33 of 2. Fig. 4 is aview in vertical section onthe line 4.-4 of Fig. 1. Fig. 5 is a view insection on the line 5-5 of Fig. 4; Fig. 6 is an elevational view of aslight modification showinghow the device may the rear of be attached toa closed car. .Fign. is a view inhorizontal section on the llne 7+7 ofFig. 6. Fig. 8 is a view showing a wiring diagram. i Q

As shown in the drawings, and referring first in particular to' theconstruction shown in Figs. '1 to 5. a support 10 is secured by clips 12to a wind shield post P. The support 10 is hollow and receives the innerend of a laterally extending sleeve 14 which as shown in Fig. 2 is heldin the support by a set screw 16. Rigidly secured to the outer end ofthe sleeve 14 is a cup-shaped member 18. Rotatably mounted in the sleeve14.- is a hollow shaft 20 on the inner end ofwhich is a miter gear 22which meshes with a miter gear 24 secured on the inner end of a end ofthe shaft 26 is a handle 30 located shaped member 38, the periphery ofwhich rotatably engages at one sidev of the periphery ofthe cup member18. Secured to and extending. from one side of the cup member 38 is ahollow arm 10 while'secured to and extending from the other side ofthiscupmemberis an arm 42 which terminates in a knob 44. Secured :to theouter end of the arm 40 is a-casi11g46,vthe fronta-nd positioned betweenthe translucent plates.

Secured to the outer face of the cup member 18 is a ring 56 ofinsulating material upon which is mounted a contact ring 58 having a gap60 in its periphery at the upper side thereof. Within the hollow arm andsupported by insulating disks 62 and 64 is a conducting rod 66.-Surrounding the upper end of this rod above the disk 64: is a spring 68which has the double function of forming a connection with oneterminalof the lamp filament and of holding thelamp bulb in its socketas will be evident'from Fig. 1. The other terminal of the. lamp filamentis connected to the metal of the lamp socket which in turn connects withthe metal frameworkso that the connection.

from this end of the filament is grounded as indicated at G in Fig. 8.The insulating disk 62 is provided with a pin 72 which engages a lug onthe interior surface of the arm 40 so asto'prevent the rod 66 fromrotative movement. Secured to the lower end of this rod is a resilientcontact finger 74 which engages the contact ring 58 in all positions ofthe arm 40 excepting its vertical position in which case the finger islocated at the gap 60. In order that the arm 40 may be held either inhorizontal or vertical position, the stationary cup member 18 isprovided with spring-pressed detents 76 which engage shallow depressionsin the inner wall of the rotatable cup member 38.

Secured .to the contact, ring 58, is an insulated shaft :20 and outthrough the support 10 toggbatteryqB. whichhas a switch S. as-

sociated. therewith, hen this switch is closed, the circuit through thelamp for most positions of the indicating arm is completed since thelamp at one side of the switch is connected to the frame .;0f thevehicle as...

indicated at G in Fig. 8. The rear of the cupvmember 18 .is closedbyiacover plate 80 securedthereto and this plate is provided with aprojection 82 having a concaved depressiontoreceive aball 84 held.frictionally iii-place by a screw-threaded cap 86 which engagesexternal: threads on, the projection.

The ball:84l carriesa frame 88 for holding a mirror 90 above which is avisor member 92 secured to the frame '88.; H The. screw threaded cap 86holds the ball 8% frictionally so.-.thatthe mirror .may be readilyadjusted into different positions. The device as shown in Figs. 6 and 7is substantially the same as that already described, the .dif-

ferenceabeing thatthe support designated. 10., instead of beingprovidedwithclipsfor securing-wit to .a. windshield post is providedwth.a. flattened portion 94: having? holestoa receiveascrews 96:.for.securing the support tothe frame F which is outside of the windshieldofa closed car. v-

The operation and advantages of our invention will be obvious from theforegoing description. The normal .position of the arm 40 carrying thesignal at vits end .is shown in full lines in Fig. 1 extendingupwardly.Whenthe arm is in this position; the lamp is not'lit since the contactfinger 7.4:- is: at the gap ofthe contact ring 58 as shown in. Fig; 5..lNhen the driver wishes to stop, slow down orturn, the arm 40'may bemoved. by means of the handle 30v and the operating connections,previously described, into different positions as shown indotted linesin Fig.1. As soon as the contactfinger 74;- is moved into engagementwith the con;- tact ring 58, the lamp is lit. If the trafficregulationsof the particularplace require thelsignal tobe displayed indownward posi tion, the arm may be-turned from upri ht j positionthroiigh 189 instead of throdgh 90. In fact, this arm may be turned allthe. Way througha complete circled :It-will thus be seen that ourdeviceis efficient for the purpose intended and is also economical inuse sincea small lamp. at the outer end of the indicating arm serves to display asignal such as a redlight signalat therear and a differentlycoloredQsighalQatIhe front, and this lamp" will not be lit when thesignal arm extends upwardly in its normal inoperative position. Bymounting the signal arm so that it. may be rotated through a completecircle, it is adapted for use to meet different traffic regulations orordi-' nances. When thesignal arm extends downwardly, the device. isadapted for a parking light, sincethe lamp; will be lit in this positionRegardless of. whether the windshield support. extends exactlyin. a"vertical direction orin an inclined. direction as iswoften the case,'thedevicemaybe readily attached theretozso that. the signal arm will:extend vertically. upward when .the lainpis not lit, and( so that. the.signal, arm. be held in either horizontal or downwardly extendingpositionwith the lamp lit. 1
